sub-headings:<\/p>\n<ul>\n<li>The case (a description of the fatal MVA, the legal\/technical issues, and my client)<\/li>\n<li>Forensic engineering investigation of the failure and the methods

motor vehicle accident (MVA)<\/strong><\/p>\n<p>The accident occurred a few years ago on a remote, snow-covered highway along the top of a seaside cliff in eastern Canada.\u00a0 A jeep-like vehicle travelling along the highway at dawn struck a pile of soil-like material\u00a0left in the travel lane.\u00a0 The driver lost control of the vehicle and drove over the cliff and into the sea.\u00a0 The driver died in the accident.\u00a0 Passengers in the vehicle survived.<\/p>\n<p><strong>Legal\/Technical issues<\/strong><\/p>\n<p>At issue, for purposes of the forensic engineering investigation, was the following:<\/p>\n<ul>\n<li>Whether or not the pile of material on the\u00a0highway was a hazard<\/li>\n<li>If it was, determine the degree or severity of the hazard<\/li>\n<li>Also, whether or not the pile of material caused the accident<\/li>\n<\/ul>\n<p><strong>Client<\/strong><\/p>\n<p>I was retained by the RCMP to investigate the accident and resolve the technical issues.<\/p>\n<h1><strong>Forensic engineering investigation<\/strong><\/h1>\n<p>There were no guidelines or well developed methods in the engineering literature on\u00a0how to investigate this type of\u00a0accident and resolve the technical\u00a0issues.\u00a0 The investigation was unique in this respect.<\/p>\n<p>Fortunately, in researching the literature, I did\u00a0find some very relevant scientific research that I was able to\u00a0adapt to my\u00a0problem with excellent results.<\/p>\n<p>My forensic engineering investigation relied on the following methods.\u00a0 The methods\u00a0will be\u00a0described in some detail in a future posting.\u00a0 I believe the following listing of methods is quite informative by itself:<\/p>\n<ol>\n<li>Take briefing on the accident from RCMP<\/li>\n<li>Review documents on the accident provided by the RCMP including police reports and survivor&#8217;s statements<\/li>\n<li>Travel to the area and visually examine the scene of the accident<\/li>\n<li>Generate a picture of the accident scene using Photoshop as it might have been\u00a0seen by the driver\u00a0moments before the accident<\/li>\n<li>Research engineering literature for methods on the investigation of obstructions on a highway<\/li>\n<li>Research scientific literature on speed bump research and design<\/li>\n<li>Research transportation authorities in North America and Europe<\/li>\n<li>Design a full scale preliminary re-enactment of the accident on bare roads<\/li>\n<li>Plan a full scale re-enactment of the accident on a snow covered test site implementing refinements to the re-enactment including safety measures derived from the preliminary testing<\/li>\n<li>Design a videotaping and measuring of the re-enactment<\/li>\n<li>Construct a re-enactment site on an airport taxiway<\/li>\n<li>Re-enact and videotape the accident on the test site<\/li>\n<li>Analyse\u00a0the\u00a0videotape for evidence respecting the technical issues<\/li>\n<li>Edit the\u00a0videotape to portray the re-enactment in a report<\/li>\n<li>Report on the preliminary findings including safety issues<\/li>\n<\/ol>\n<p><strong>Description of methods
